Is there evidence that the use is having an impact on the target species?: Wild species sourced from its natural habitat

Has an assessment (or judgement) of sustainability of the use of the target species from an ecological perspective been recorded?: Yes, considered sustainable

Details of assessment carried out: This CITES NDF report.

Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: The Australian CITES Scientific Authority has determined that the aforementioned annual harvest levels for a period of three years from 14 September 2014 are sustainable and unlikely to be detrimental to the species.

Has an assessment (or judgement) of sustainability of the use of the target species from an economic perspective been recorded?: not recorded

Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species

 Species level reporting in log books  Further measures to reduce incidental capture and post release mortality as practically appropriate to specific fisheries and gear types  Landing of sharks with fins naturally attached  Reporting of discards to species level  Maximum size limits  Trip limits  An improved understanding and management focus on IUU.
